Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed March 28. 1906. Elerial No. 262,518.

stock in the county of McHenry and State of Illinois, have invented certain new and useful Im rovements in Ty e-Writer Carriages; an we do hereby (1801 21113 that the followin is a full, clear, and exact description thereo reference being had to the accompanying drawin s, and to the letters of reference marke specification.

This invention relates to improvements in sup orting means for the paper-guides; gui erollers, and scale-bar of a type-writing machine carriage by which auxiliary supports are provided for the said paper-guides, the guide-rollers and the scale-bar between the ends of the same, so that in extra long carriages said parts will be prevented from bending or flexing outwardly or away from the platen in the operation of insertin the pager into or feeding it through the mac ine.

ur improvements are herein shown as applied to the carriage of an Oliver type-writing machine; but the same may be ada ted to other machines to which they are app icable.

As illustrated in said accompanying drawings, Figure l is a view in front elevationof the spar-carriage of an Oliver type-writing mac iine showing our improvements applied thereto. Fig. 2 is a cross-section of the carriage, taken upon line 2 2 of Fig. 1. Fig. 3 is a perspective view of the central part of a lower paper-guide. Fig. 4 is a face view of the auxiliary supporting devices in the central part of the carriage, the same bein shown in face view and on a much enlarge scale. Fig. 5 is an enlarged detail cross-section taken upon line 5 5 of Fig. 4. Fi 6 is a erspective view of the holding-clip %or the ower guide-roller separate from the other parts. Fig. 7 is a perspective view of the supporting-aim for the lower guide-plate separate from the other parts. Fig. 8 is a perspective view of a device for holding the out guide-plate and scale-strip from bending or flexing outwardly, made in one piece instead of in two separate parts.

As shown in the drawings, A designates as a whole the carriage of an Oliver typewriting machine, A the platen thereof, and A A A the nresser-rollers by which the. pa-

a and longitudinal frame-bars a a. the front edge of the front lower bar a is 6 thereon, which form a part of this per is guided about the platen and by which it is he d properly in place against the platen duringthe printing operation. Said carriage comprises in its general features end-platesia Upon formed the rack-bar a of the letter-spacing mechanism.

B designates a curved guide-plate or papershield located at thefront of the platen between the upper and lower, front presser-roll- '65. are A A, by which the advance mar in of a sheet of paper which is being inserte into a machine is guided as it passes from the lower to the up er presser-roller'. The said front presser-roflers are mounted in 'a frame com- 7c prising end pieces 0 C and 8'. ion itudinal bar C, which extends between sai, end pieces. Said bar C is connected with said end ieces by means permitting ittorocli'on its on itudinal ax1s,;and the guideB is afiixed at its upper margin to said at and depends there-. from. Said guide is thus free to swing at its lower margin toward and from the platen. The shafts of saidpressersrollers are rotatively mounted in the upper and lower ends 8c of said end pieces 0 C of the frame. The frame thus car ing the presser-rollers A A" and the guide-p ate B is movably nounted in the carriage of the machine by means of studs a a, projecting laterally from said .end pieces and entering forwardly-opening notches in the end late a" a of the carria eframe. The parts thus described are he] "in place and pressed toward the platen by means of leaf-springs B B, which are attached at their lower ends to the carriage and beat at the upper or free ends a ainst the ends of the I guide-plate B, the springs permitting the frame, rollers A A and the guide-platetO yield b'odily away from the platen to accorn- 5 modate the thickness of a number of sheets of paper and also permitting the loweraed e of the uide-pl ate to yield away from the p aten fort esimepurpose. I v

The lower presser-roller A and the. lower :00 guide-plate H are supportei tjby two springarms arranged horizontally and adjacent to the end plates a a of the carriage and secured at their rear ends to lugs on said end plates, one of the arms being indicated G -w and its supporting-lug a being shown in 2. D indicates a scale-strip which exten a longitudinally over the platen at the rear of 7 which latter is grooved or reduced in diamel 'tal bar a and is provided with a slot is,

. fits or rests.

ig. 3, equal throu h which is inserted a holding-screw k, by wfiich the arm is adjustably connected with said bar.

The arm K, arranged as described, with its end portion in contact with the bearing-surface a at the part thereof opposite or remote from the platen A, serves to resist the outward movement of the central part of the lower feed-roller in a direct ion away from the platen. Said arm K is made of spring metal, so that it acts with springprcssurc against the lower 'presser roller and enacts with the supporting-springs G G of said roller to press or hold the same yicldingly against the platen.

A device is mployed for supporting the entral part of the lower guide-plate H as follows: L is a secondary supporting-arm which is attached to the rear or free end of the arm K and extends forwardly and upwardly therefrom in position for bearing-contact with the bottom surface of said guide plate Il. Said arn'i L shown as shaped or formed to conform to the curvature of the outer curved or bearing portion is of the arm K and as secured to the outer or lower face thereof, with its forward end extending through a longitudinal slot 1*, formed in the said arm K between said curved hearing ortion In thereof and its horizontal part, w icll is secured to the cross-bar u. of the carriage. The forward or free end of said arm L is shown as shaped to form a bearing portion Z, which rests and its against the curved lower portion of the guide-plate ll, the intermediate portion of said supporting-arm L be tween its rear curved part Z and said forward part L being inclined upwardly and forwardly, as clearly shown in the drawings. In order to hold the bearing end I of the arm L from shifting laterally on the guide-plate H, the stiffening-bar or rib h, which is usually provided on the bottom surface of said guidelate, is shown as provided with a notch h,

in width to the end Z of the sup- L, and within which said end I The said arm L is also preferably made of spring metal. so that the resiliency of said arm, together with that of the porting-bar arm K, to which it is attached, afl'ords conplate to siderable degree of yielding movement in the central part of the plate H, permitting said yield downwardly or away from the platen, when the ends of said guide-plate, to

gather with the ends of the roller A, are depressed by the downward movement or yielding of the spring-supporting arms G G, by which said guide-plate and the said lower roller are sustained.

While the means illustrated for holding the scale-strip from rising or bending in its center embrace a clip attached to the bar C and a supporting-arm i on the carriage en gaging said her C, so that the said clip constitutes, in effect, a continuation of said arm F, yet the same general result will be obtained if the said clip be directly attached to or forms an extension of the arm 1 instead of being. made separate from said arm and connected with the same thronghthe mediunrof the said barC. A construction of this kind. referred to is shown in Fig. 8, in which N indicates an arm adapted to be attached to the frame-bar a in the same manner as the arm I", hcreinhefore described, and provided at its upper end with an integral upwardextension N, terminating in a horimentally-bent part which is provided near its rear end with a pin or stud 1t and which is adapted to extend to and engage the scale-strip l) in the same manner as does the clip 1. hercinheforc described. The said arm N is in this instance providcd at its side edges with rearwardly-bent integral prongs n n, located in position to engage the bar C, so as to hold the latter from rising, said prongs taking the place of the hooked upper endf of the said arm 1*. (Shown in Figs. 1, 2, 3, and 4.)

We claim as our invention- 1 The combination with a paper-carriage, a platen, a longitudinal paper-guide and a scale-strip, of a supporting-arm attached to a longitudinal member of the frame and engaging the paper-guide, and a clip constituting a continuation of the supporting-arm and adapted to bear against the scale-strip at a point between its cnds to hold it from springmg outwardly away from the platcn.
